Configuring NetRAIN on TCS 5.1 nodes

Hi, folks. I'm working on a TruCluster (5.1) with two ES40s, each with 4 CPUs, 8GB memory, dual-KGPSAs hooked to 104 disks in an RA8000. Node 1 has dual ethernet cards, Node 2 has two 10BaseT and two fiber ethernet cards. My issue/question today deals with NetRAIN configuration on these two.

We installed 5.1 on the first node and configured the array with no problems. The clu_create procedure copied over the single-node configuration (including the nr0 NetRAIN config). We did a clu_add_member like usual for the second node and booted the genvmunix on the member boot drive. The configuration ran and did the clu_netsetup script. Of course, the netsetup script would not allow us to configure a NetRAIN at that time. We tried several approaches at this point:

The first approach was to not configure any network interfaces in clu_netsetup. We brought the second node up in single-user mode, copied over the rc.config from the member1/etc to the member2/etc directory. We edited the node-specific stuff in rc.config then brought the system from single-user to run-level 3. The system did a panic and halted.

OK, second approach was to do a clu_delete_member, then clu_add_member and re-install the node. When we ran clu_netsetup, specified the ee0 device and came up ok. We then used sysman to de-configure ee0 and configure ee1. Then we did:

ifconfig nr0 <ip address> netmask 255.255.0.0 add tu0,ee0

just like the array configuration on the first node. As soon as we hit enter, node 2 paniced.

So, this is where we are: we can bring the cluster up with nr0 working properly on node 1, but only with a single ethernet board (ee0) on node 2.

Questions:

1. Does anyone see anything obviously wrong with what we're doing?
2. Is there a documented procedure anywhere for use of NetRAIN in a cluster environment? the website has the docs for regular Tru64, and the TCS docs only say to make sure niffd is started on the cluster node.

Thoughts?

Cheers,
Ed.
